New snowfall of 1 to 3 inches, beginning early on February 13th, and existing deep snow cover, combined with strong northwest winds which developed on February 14th, to produce blowing and drifting snow which reduced visibilities in some areas. The developing slick roads resulted in several accidents, which continued after the snow had ended and visibilities had improved.
